pulse The word pulse has many shades of meaning, but most of them involve something characterized by short, rhythmic bursts. If you’re angry, the muscles in your jaw might pulse — meaning they contract quickly in short bursts. Pulse can be a noun that describes the rhythmic pumping of blood through your veins and arteries. You’ve probably had a nurse take your pulse as a way to measure your heart rate. Pulse can refer to other things that have a rhythmic beat, like the pulse of dance music or a pulse of flashing light. The verb describes something that throbs, literally or figuratively. Your blood will pulse through your veins, or a busy city may pulse with life.

PULSE Primary Meanings of pulse. 1  n the rhythmic contraction and expansion of the arteries with each beat of the heart. 2  n the rate at which the heart beats; usually measured to obtain a quick evaluation of a person's health. 3  v expand and contract rhythmically; beat rhythmically. 4  v drive by or as if by pulsation.

pulse Definition of pulse. 1  1a : the regular expansion of an artery caused by the ejection of blood into the arterial system by the contractions of the heartb : the palpable beat resulting from such pulse as detected in a superficial artery; also : the number of individual beats in a specified time period (as one minute) a resting pulse of 70.

What is a Wave? A wave can be described as a disturbance that travels through a medium from one location to another location. Consider a slinky wave as an example of a wave. When the slinky is stretched from end to end and is held at rest, it assumes a natural position known as the equilibrium or rest position.

What is a Wave? What is a Wave? Definition of a Wave. a disturbance or variation that transfers energy progressively from point to point in a medium and that may take the form of an elastic deformation or of a variation of pressure, electric or magnetic intensity, electric potential, or temperature.

Reflection of a Pulse at a Free End When the pulse reaches the end of that medium, what happens to it depends on whether the medium is fixed in space or free to move at its end. For example, if the pulse is moving through a rope and the end of the rope is held firmly by a person, then it is said that the pulse is approaching a fixed end.

Energy Transport and the Amplitude of a Wave Energy Transport and the Amplitude of a Wave. As mentioned earlier, a wave is an energy transport phenomenon that transports energy along a medium without transporting matter. A pulse or a wave is introduced into a slinky when a person holds the first coil and gives it a back-and-forth motion. tripling of the amplitude of a wave is indicative of a nine-fold increase in the amount of energy transported by the wave. And a quadrupling of the amplitude of a wave is indicative of a 16-fold increase in the amount of energy transported by the wave.

- Definition The time from the start of a pulse to the end of that pulse, the actual time that the pulse is “on”. Units seconds—any unit of time. Determined By Sound source. Pulse duration is determined by multiplying the number of. cycles in the pulse and the period of each cycle.

Nuclear electromagnetic pulse An electromagnetic pulse (commonly abbreviated as EMP, pronounced /iː.ɛm.piː/) is a burst of electromagnetic radiation. Nuclear explosions create a characteristic pulse of electromagnetic radiation called a nuclear EMP or NEMP.n nuclear EMP all of the components of the electromagnetic pulse are generated outside of the weapon. For high-altitude nuclear explosions, much of the EMP is generated far from the detonation (where the gamma radiation from the explosion hits the upper atmosphere).

pulse light year - Not a length of time but a distance, the distance a pulse of light travels in one year (about 5.88 trillion miles). pea - Comes from Greek pison, pulse, pease.. asphyxia - Its original meaning was stoppage of the pulse. ictus - The beat of the pulse, based on the Latin word for stroke..

radial pulse ra·di·al pulse. 1  the pulse as appreciated at the radial artery usually in the wrist. 2  A palpable rhythmic expansion of the radial artery on the volar aspect of the wrist over the distal radius. 3  A palpable rhythmic expansion of the radial artery on the volar aspect of the wrist over the distal radius.

femoral pulse 3. the beat of the heart as felt through the walls of arteries. What is felt is not the blood pulsing through the arteries but a shock wave, generated by the abrupt ejection of blood from the heart, that travels along the arteries. The arterial pulse wave can be measured by a sphygmograph.

- The term pulse, as used by the United Nations ' Food and Agricultural Organization (FAO), is reserved for crops harvested solely for the dry seed. This excludes green beans and green peas, which are considered vegetable crops.or the medical term, see Pulse. A pulse (from Latin: puls, from Ancient Greek πόλτος: poltos  porridge ), sometimes called a grain legume , is an annual leguminous crop yielding from one to twelve seeds of variable size, shape, and color within a pod.

What is the difference between a pulse and a wave? A pulse is a wave packet containing broad range of frequencies. A pulse (wave packet) is a localized disturbance that results from the sum of many different wave forms. The wave is the transport of disturbances in space, not associated with motion of the medium occupying this space as a whole.s there is but one pulse, the wave travels through water at velocity v and that one wave's energy compresses and releases water as the wave travels through the water.

Electromagnetic pulse An EMP arises where the source emits a short-duration pulse of energy. The energy is usually broadband by nature, although it often excites a relatively narrow-band damped sine wave response in the victim.

wave n. 1  A disturbance traveling through a medium by which energy is transferred from one particle of the medium to another without causing any permanent displacement of the medium itself. 2  A graphic representation of the variation of such a disturbance with time. 3  A single cycle that is representative of such a disturbance.
